CDU-AC5

2.1 Features and Capabilities

 Graphic Hosting. Hosting of schematics which can real-time data fields retrieved from

the locally connected CDUs via the LonWorks network. Adjustment of set points and other configuration property values is provided with relevant security schemes. Schematics can be viewed from Windows Internet Explorer, and achieved with the support of a signed ActiveX control.

 Alarming & Re-transmission. Generation and storage of alarms from local CDUs. Re-

transmission via E-mail or SMS (requires GSM Modem).

 Data Logging. High capacity logging to miniSD card. Multiple sources and log intervals

are supported.

 SNMP. SNMP agent support, providing a monitoring solution to existing network

management systems.

 MODBUS. MODBUS slave support via a RS-485 serial communication link, providing a

monitoring solution to any Building Management System (BMS) that supports MODBUS RTU protocol.

4.2 Local LonWorks Network

The CDU-AC5 communicates with connected CDUs over a LonWorks twisted pair network. A typical network is shown in below,

4.3 Accessing the CDU-AC5

The CDU-AC5 can be accessed from a client PC running Microsoft Internet Explorer 5 or above. The following security options must be enabled within Internet Explorer,

 Scripting  Active X Controls

The CDU-AC5 communicates using a number of standard and non-standard TCP ports. If access is to be gained through a firewall, the following ports are should be open.

 20-21  80  44000 – 44002  50000 – 50010

The default IP configuration of the web server is

 IP Address 192.168.11.22  Subnet Mask 255.255.255.0  Default gateway 0.0.0.0

4.4 Installing the Active-X control

When accessing a CDU-AC5 for the first time, an Active-X control will be downloaded and installed on the client PC. The download is an automated process - the user only needs to confirm several security prompts.
